Test of Model RG-3 Radio Receiving Equipment Range 1000 to 20000 Kilocycles
Abstract
To obtain performance data on modified being designated as Model RG receiving equipment, and to ascertain quantitatively the exact improvement in performance resulting therefrom. By the substitution of types 38036 and 38037 tubes for the type CW1344 tubes originally used, the sensitivity of the receiver is greatly improved. Due to the increased gain and luck of adequate shielding, there is considerable interaction between stages, which increases with frequency. However, this does not become serious enough to preclude good operating results below the upper end of coil 5. At this point, tuning becomes more or less critical, at the lower end of coil 6 very critical, in the middle of coil 6 operation is more or less unstable, and at the high end of coil 6 unstable. With the rearrangement of wiring as suggested under test (a) end a slight modification of the tickler minding in coil 6, it is believed satisfactory operation could be obtained on coils 5 and 6.
